AT A GLANCE
Why go?
Thanh Cong Lake (Hồ Thành Công) is a clear, stone-embanked sheet of water in the heart of Hanoi, cradled inside Indira Gandhi Park at the meeting point of the Láng Hạ, Huỳnh Thúc Kháng, Nguyên Hồng and Thành Công streets. Of the park's roughly 8.6 hectares, the lake itself covers about 5.9 hectares, making it one of the inner city's green lungs and a place where the capital's everyday rhythm is at its most relaxed.↗↗↗
It is not a monument or a museum, and that is part of its charm. Come at dawn or in the cool of the evening and you join thousands of locals walking, jogging and exercising around a 1.2-kilometre loop, with a fountain playing in the middle of the water and a bust of the Indian prime minister the park is named for standing watch toward the main gate. It is a genuinely lived-in slice of Hanoi, free to enter and open all hours.↗↗
A lake dug by student hands
Thanh Cong Lake is, remarkably, a piece of collective labor rather than an ancient natural landmark. It took shape between 1984 and 1987, the product of public-works campaigns by students from Hanoi's Transport, Polytechnic and Culture universities. In an economically hard decade, they cut the earth into blocks and hauled it out by hand through the clay, forming this regulation lake at the same time as the neighboring Ho Ngoc Khanh Lake. For the students of that era the lake remains a source of personal pride, and it explains why the water is ringed by a careful stone embankment, later reinforced in a 1997 renovation.
